.BLANK-LOCATING MECHANISM.

Application filed January 28, 1524. Serial No. 688,953.

To all w/mme't many concern:

Be it known that I, ABRAHAM .NovIoK, a citizen the United States, anda'resident of Flushing, county of Queens, and

State of New York, have invented certain new and useful ImprovementsinBlankl ioeating Mechanisms,- of which the following is aspecification. I V

This invention relatesto meansfor align ing and centering blanks,particularly enve-lopeblanks in envelope making machines and the like,and holding them incentered position until they are engaged bysubsequent operating mechanism. I

In the preferred form of embodiment of the invention, the aligning andcentering of the blanks is accomplished by a pair of jogging fingers,which fingersare given an orbital movement, the operating stroke ofwhich is in the plane of the blanks and the return strokeof which is outof the plane of the blankssothat during this return stroke a new blankmaybe inserted into position for being acted upon by the jogger. Adistinct saving oftime is thus made and the machine is rendered capableof a high speed of operation. I v

In accordance with a further featureof the invention, the joggingfingers are arranged tomove in convergingplanes so that the operation ofthe jogging fingers causes not only alignment of the blank but centeringthereof as well. This feature is of particular importance for blankswhich are relatively long and therefore difficult to center.

According to still another feature of the invention, mechanism isprovided for impressing on the joggers movement which is translationalas distinguished from rotational, so that adjustment of the mechanismfor blanks of different seizes may be made without disturbing theorbitalmovement of the jogging fingers.

Various other features and advantages, included within the objects ofthe invention, will appear as the description of the invention proceeds.7

Certain features disclosed but not claimed herein are disclosed andclaimed in my pending applicatiom-Serial.No. 673,049, for bot-tomfolding mechanism, filed November 6, 1923, and in my pendingapplication, r Serial No. 631,576, for mechanical movement, filed April12, 1923.

Referring now tothe drawings which illustrate a preferred form ofembodiment of the invention, together wit-lrsuchpartsof the envelopemaking machineas are necessary toillustrate the operation of the same,

. ward on ,thebelt 2 under the weighted friction rollers 8, whichfri'ct-ionally hold the blanks, upon the belt so that they travelforward therewith, but permit them tobe centered relative to the formingblades 3 and the folding mechanism.

.Atthelower end of the forming blades 3, .theblanks contact with stops 9which are mounted on a hart) which constitutes apart of the lower flapfolding mechanism described in my co -pending application. Serial No.673.049, filed November 6, 1923.

The position of stops 9 on bar 9 is rendered adj ustable by means ofscrew woo-operating with-a. series of threaded holes 11 in the bar 9 sothat the various seizes of blanks may be accon'imodated.

As the blank isv brought to rest against the stops 9, it is centered andbroughtinto proper alignment by the action of thejoggerfingers 12, sothat the blank may then be accurately foldedinto the desired shape orsubjected to other Operations necessary for forming the desiredenvelope.

Each jogging finger 12 is provided with an Operatingor tip member 13adjust-ably mounted upon the end of the .fin'ger12 by meanes of atelescoping tube 13 which is held in ,position by a set screw 18". jEachfinger 12 is bent into ,a-right angle 12, and the end opposite themember13 ismounted for longitudinal and angular adjustment in a holder14 Which is provided with aset and slides 19 and 19.

screw 1 1 and a key 14 for loosening or tightening the screw 1-1 whenthe finger is to be adjusted.

The holder 1% is carried on the end of a slide 15 which passes through aguide or housing 16 provided with a cover plate 16 and is provided witha roller 17 at the end opposite the holder, for cooperation with a camsurface to be described later. Projecting from one side of the housing16 is another housing or guide 18, with a cover plate 18 for the slide19 which carries a finger 2O projecting into a slot 21 in the slide 15.The other end of the slide 19 is provided with an oval shaped slot 22for receiving one end of the flattened rod 23, the other end of which isreceived in a similar slot 22 in the slide 19" of the other half of thejogger.

The guides 16 and 18 are rigidly mounted upon a stationary part 24 ofthe machine, upon which is also mounted the rod 25 can rying the lever26 for operating the rod 23 The lever 26 comprises a hub portion 26,which turns upon the rod 25, an arm 26 connected with the rod 23, and anarm 26, carrying the cam roller 27 for cooperating with the cam 28. Aspring 29 holds the roller 27 in contact with the cam at all times.

A cam shaft 30 carries the cam 28, the cam members 31 and 32, and othercams for operating the various parts of the machine in properly timedrelation.

The operation of the jogger is as follows:

At the initial position illustrated in Figure 1, the tip members 13 ofthe jogging fingers, are approximately in the position illustrated inFigure 3. When the rollers 17, which are held in contact with the cams31 and 32 by the springs 33, travel to the low side 31 of the cams 31and 32, the fingers 13, which are then in the plane of the blank, aredrawn downward in converging planes Z (Figure 2), which intersect theangle between the top and side flaps of the envelope blank. The blanksare thus aligned against stops 9 and because of the converging componentof the downward movement are si multaneously centered laterally. Thelatter feature is of particular importance when the blanks which aresubjected to the align ing operation are relatively long, as will bereadily understood.

In Figure 1, the movement of the jogging lingers is illustrated by thediagram A, the direction of movement being illustrated by the arrows, Itwill be observed during the downward movement described above, the tipsof the jogging fingers are in the plane of the blanks. At the end ofthis movement the fingers are withdrawn from this plane, this withdrawalbeing brought about by cam 28, the low side of which at this time passesunder roller 27 of lever 26, thus permitting spring 29 to turn the leverclockwise in Figure 1 so as to draw out the slide 19 and draw the slide15 toward the bottom 16 of the guide 16. At the completion of thismovement the tips 13 are to the rear of the plane of the blanks andwhile in this position, they are returned to the upper part of theirstroke by the action of roller 17 which now passes over the high side 31of cams 31 and 82. Because of the fact that the jogging lingers duringthe entire period of their return movement are behind the plane of theblanks, the blank previously aligned may be withdrawn from its positionstops 9 (this withdrawal being effected by mechanism indicated at 9 inFigure 1, the construction of which, however, need not be considered forthe present purpose) and a new blank may be inserted into position foralignment so that considerable economy oi time and therefore rapidity ofop ration, may be realized. fit the end of the upward movement, thejogging fingers are again caused by cam 28 to move forwardly into theplane of the blanks, whereupon the entire cycle of operation isrepeated.

It may be observed here that the length of the slot 21 is greater thanthat of fiHQEJ O of slide 19, so as to permit the slide 15 to movelongitudinally with reference to slide 19, and the slots 22 in slide 19are longer than the flattened sides of rod 28 topermit rela tivesidewise movement of the rod in the slots.

it is to be noted that the adjustment of the lingers 12 by sliding themin and out of the holder 1-2; or by turning the holder relative to theslide 15, does not disturb orchange the orbit A through which thejoggers travel, asthat is determined by the path of movement of theholder 14 on the end of slide 15, which path is unaffected by theadjustment. While the path traveled by the poll vs 13 has been referredto as an orbit, he movement of the points 13 is not one of rotation butone of translation and comprises four compon nts. namely. downward,rearward, upward and forward, and all the movement is in a planesubstantially as indicated at Z in Figure 2, the downward movement beingin the plane of the envelope blank and the upward move ment being in.the rear of this plane.

llhile the movement of the jogger under the influence of too high andlow points of the cam has been described, it is to be understood thatthe shape and position of the cams and the shape of orbit A asillustrated and described, is not intended to be mathematically correct,but is largely diagrammatic for the purpose of illustration.
